Suggestion for new product/service

I do a lot of Snowboarding, skiing, and single track bike riding. I always wear my Gopro when doing so. I realized that there is one thing missing from the footage. My Idea would allow riders to take the best shots of themselves hands free. It would also create more revenue for GoPro and participating parks.

Here's how it would work. Once you arrive to a participating park you would sign in via a newly designed gopro app. Through out the park there will be hidden gopro cameras at each feature to capture your epic ride. At the end of your ride you would go to the app and purchase the pictures that you like best or even a video montage of every feature that you hit.
